I like the color of the fall leaves, but the clouds are a little overexposed and the image is noisy, so decreasing the ISO could have been better.
Awesome picture! Great depiction of a stable cloud formation. Good contrast too
I really like this photo and the colors in the trees, although they can be distracting from the clouds. I would of liked to see this photo taken at a higher elevation. Overall great work!
Really like the coloring and framing the trees provided in this photograph. The change of color of the sky is very interesting.
1. The image is pleasing and bright.
2. The flow is clearly demonstrated.
3. The photographic technique is nice and the blue hue of the sky is great.
I really like this image! You’ve captured a full range of blues in the sky, with the leaves changing on the trees in the foreground, the clouds really pop. This picture really feels like a crisp, cool fall morning. There is a little noise in the image, likely from setting the ISO a little too high. It’s really not distracting though. Great job!
– Great photo I really like the colors in this.
– I’m sure people have already said, but the ISO does make it a little blurry.
– Perhaps getting rid of some of the negative space towards the top right corner might help show more of the clouds.
Nice blues in the sky and yellows on the trees. I do find the frame ending halfway down the trees a little awkward and the graininess from the high ISO a little distracting. Definitely take some time with your camera to figure out why your couldn’t get the right exposure with lower ISOs. The camera may not be in an automatic mode.
I like how sharp the tree in the foreground is in the higher res photo. It has a feel like the clouds are rolling in from the left. good color tones as well.
I like the foreground trees especially because this is not a sunset so you get the different colors through the trees. Not sure if i like the bright bottom right section of the image, but very interesting clouds with a vivid blue skyline
Th sharpness of the photo is a little harsh, did you add sharpening to the photo? Perhaps you could have traded the shutter speed for the ISO, I would have used a shutter speed of about 1/30 or so, and you could have probably even gotten away with an ISO of about 100 or 200. The color contrast of the trees to the clouds to the sky is really nice.
picture looks a little grainy but I love the bright blue in the sky. The contrast from the orange leaves is absolutely gorgeous. The trees on the bottom give it a nice bordering frame too.
Great colors! I like the Autumn feel. The clouds are interesting as well. Particularly, I like the long, thin one above the trees. It’s a little grainy in the right corner, but I think I like it. It almost looks like a postcard or something.
You captured some really cool clouds and the changing trees look really cool. I feel like the focus is a little off, but maybe that’s simply a byproduct of the ISO value that you used.
Art: I like the range of colors from the yellow in the tree to the deep blue in the top
Flow: I wonder what the fuzzy looking dots in the middle right of the photo are
Photo technique: Good contrast range
Art: I really like the color contrast between the changing colors of the trees and the bright sky.
Flow: The flow is quickly understandable and easily recognized.
Photographic technique: The focus of the Clouds is great, and the depth of field was also very well done.
The contrast between the trees turning colors and the white clouds is very nice. The ISO might be a bit high for this image, there are some grains in the sky. The transition between the deep blue and white in the sky is visually appealing, nice job.
I like how you kept the trees in the image. They give a great contrast in colors. Cool how the blue in the sky shifts from dark to light as you look further right. Nice bright white clouds.
I like how the trees below bend around the bottom of the photo. This gives the impression that the image is bending with the trees. a really nice tone of blue in the upper corners of the photo.
The ISO seems a little high adding to the noise. The change in hues from dark blue to light blue (almost white) is nice.
The image is semi blurry, however, there is a wide range of colors. The fall leaves help create an aesthetic appearance. Overall great contrast and stunning image.
This photo has a great foreground! The fall colors make this playful and give a lot of contrast that I think some of the other images are missing. A little bit of noise is distracting, but the overall feel of the image is preserved. My favorite part is the shift in color from the bottom right to the top left of the image.
Awesome pic, really like the trees and the color of the leaves. They are a good contrast to the crisp clouds and blue sky.
First comment is to try and adjust your post to show the higher resolution image. Try using the “featured image” tool in the post editor. There is almost a fish-eye effect that gives the photo a very cool effect.
